5 Sheets-Sheet WATER CLOSET BACKGROUND OF TEE INVENTION The inventionrelates to an improved water closet having a water storage tankpositioned within a wall so as to conserve floor space. In the past,installations of this type have not been satisfactory due to themechanical features of the valving system which require occasionalreplacement of parts thereby necessitated the presence of a removablewall panel to obtain access to the water storage tank. Additionally,certain valve forms after extended use fail to seat properly and oftenwere incapable of being unseated to permit discharge of the water. Thehydrostatic pressure of the water in the tank acting against the floatvalve, which often takes the form of a ball, prevented the ball frombeing unseated or, if it was unseated often would reseat the ball andprevent the ball from rising to a flotation position whereby the tankcould be discharged. Similarly, most of the previous forms did notprovide an antisyphon means to prevent the re-circulation of dischargedwaste into the supply source of pressurized water.

SUMMARY The invention relates to an improved water closet, andpreferably a water closet which can be fabricated from plastic materialswhich are relatively light Weight and will be relatively maintenancefree. It is an object of this invention to provide a generally oblong orrectangular elongated water tank capable of being positionedintermediate two adjoining wall sections to conserve floor space. Thetank employs the floating valve system in which a pair of float valves,one in the form of a ball, is positioned adjacent the lower end of thetank and the second in-the form of a cylindrical member having afrusto-conical upper configuration, are adapted to cooperate with andseat and seal complimentary valve seat members at the upper and lowerend of the tank. The invention also contemplates means for unseating thelower ball to permit discharge of the fluid from the tank as well as ameans for over coming the hydrostatic pressure which normally preventsunseating of the ball from the lower discharge seat. The invention alsocontemplates a novel antisyphon means to prevent contamination of thewater supply.

Thus, it is an object of this invention to provide an improved watercloset having the water tank positioned intermediate the adjoining wallsections with an improved valving system for use in such a tank. Thetank is simple in construction with relatively few moving parts whichare substantially maintenance free. Another object of the invention isto provide a valve releasing mechanism which can be removed from thewater tank without turning off the water supply. A still further objectof the invention is to provide such a water tank which is economical tofabricate and because of its design facilitates ease in installation.

Referring more specifically now to the accompanying drawing andparticularly to FIG. 1, a water closet installation of the typecontemplated by this invention generally includes a toilet bowl 10, awater closet tank 12, an inlet supply 14, a stack or soil pipe 16 andoperator means 118.

The toilet bowl 10 is of a type well known in the trade for a flush wallmounting. It is in the present instance spaced intermediate verticalwall studs 20 and supported by an inset brace 22 set into studs 20.

The tank 12 is of a general rectangular shape and may be supported oncross member 24 which is suitably braced as by angle brackets 26 betweenadjacent studs 20. The tank in the present instance can be manufacturedfrom a variety of materials ranging from the normal cast iron or sheetmetal to reinforced plastic as shown in FIGS. 3 through 7. As seen inFIG. 2 in the preferred embodiment, two pairs of longitudinallyextending ribs or projections 32 and 34 respectively extend forsubstantially the entire length of the tank and project inwardly fromthe back and front walls respectively and are positioned intermediateand spaced from the lateral sides 28 and 30 respectively. Whileprojections 32 and 34 are in opposition to one another, they arelaterally spaced apart and spaced in opposition as well so as to provideaccess between the side portions of the tank. These projections define acentral restric tive portion or cage 36, for purposes best set forthhereinafter. At the lower end of the tank in cage 36, as best seen inFIG. 3, there is provided a coaxial aperture 38 through the bottom ofthe tank. For ease in manufacture, there is provided a seat member 40which extends through aperture 38 and projecting beyond either side ofthe tank bottom 37. Member 40 on the inside of the tank is preferablyco-extensive in area with the internal dimensions of cage 36 and has atransverse lower shoulder 42 which seats against the inner surface ofthe bottom of the tank. The upper surface 44 of seat 40 is disposed at aslight angle relative to the bottom of the tank, for purposes best setforth hereinafter. Extending downwardly from adjacent shoulder 42 is acylindrical portion 46. A central or first bore 48 traverses the entirelength of seat member 40. Cylindrical portion 46 is preferably threadedboth internally and externally. A second bore 50 traverses the frontside of seat member 40 and communicates between bore 48 and the frontside of seat member for purposes best set forth hereinafter. Seat member40 may be maintained in position relative to the tank by suitable meanssuch as sealing washer 52 and ring 54 which is provided with threadscomplimentary to the exterior of cylindrical portion 46. Extendingupwardly into and threadily engaged with bore 48 is discharged pipe 56.

The first valving member used in conjunction with member seat 40 is aresilient, floatable, preferably hollow substantially impervious ballhaving a diameter greater than bore 48 but less than the internaldimensions of cage 36. Ball 60, of course, is greater in diameter thanthe distance between opposing projections 32 and 34 and is therebycaptured within the cage 36. Ball 60'is prevented from lateral movementbut is capable of vertical movement within cage 36.

A cover 64 is provided at the opposite or upper end of tank 12 forclosing the upper end of the tank. Said cover 64 may be suitable seatedand sealed against the upper end of tank 12 as by the normal gasket, notshown, or if tank and cover are plastic by heat sealing, adhesives, orepoxy-resins, as at the juncture indicated at 65 in FIG. 4.

Inlet supply pipe 14 extends vertically along the side of stud 20opposite from the location of tank 12 and is teed off as at 68 andprovided with a suitable header 70 to prevent knocking and pressurevariations. stub 72 extends through the cover 64 to provide access tothe tank 12.

Adjacent cover 64 and located within central portion 36 is shut offmechanism 80. Shut off includes a vertical member 82 which is externallycomplimentary to the internal dimensions of cage 36 defined by the frontand back walls of the tank and projections 32 and 34. A centrallongitudinally extending cylindrical bore 84 is provided which issuitably threaded to accept the threaded end of stub 72. At the lowerend of bore 84 there is provided a conical counterbore or seat 86 withits broadest portion opening into the interior of the tank 12 andproviding a second seat in opposition to seat 40.

A second float 86 which cooperates with seat 86 is generally cylindricalin conformation, semi-rigid in construction and hollow at its upper end88. Upper end 88 is further provided with a conical outer surfacesubstantially complimentary at the conical seat 86. At the apex of theconical portion 90 there is provided an integral finder portion or nose92 which is generally arrow shaped in cross section but cylindrical whenviewed in plan. At the bottom end of float 86 there is provided aconcave undersurface 94 for purposes best set forth hereinafter. Float86 can be suitably constructed of a plastic material and is solid andthereby weighted at its lower end and hollow at its upper portion 88 sothat it is susceptible of concentric floatation along its vertical axis.

Referring once again to the lower end of the tank and in particularoperator means 18. Operator 18 is generally cylindrical in configurationhaving a body and a head 102 at the outer end thereof. Intermediate itslength but spaced closer to the front end, as viewed in FIG. 3, is athreaded section 104 adapted to be complimentarily accepted within athreaded aperture 106 of the tank 12. Aperture 106 is positioned inregistry with bore 50 of seat 40 so that operator 18 extended throughbore 50 but terminates short of bore 48. Body 100 is provided with'athroughbore 108 which is counterbored at the head end so as to provideshoulder 110. It is also counterbored at the front end and provided witha conical seat 112 which communicates with the through bore 108. Locatedwithin bore 108 is a stem 114 which extends through bore 108 and thecounterbored portion and is provided at its outer extremity withsuitable threads 116. Integral with the left end of shaft 114, as viewedin FIG. 3, is the unseating mechanism or driver 118. Driver 118 isconical in configuration at the point of its juncture with shaft 114 andis complimentary to seat 112. The remainder of driver 118 iscomplimentary to and axially moveable within the counterbore at thefront end of operator 18. The front free end of driver 118 is providedwith a sloping semi-concave face 120 which terminates at the upperextremity in a sharp point 122 for purposes best set forth hereinafter.At the opposite extremity or head end of shaft 114, a button member 126having a threaded internal bore complimentary to threaded portion 116 isseated thereon. The inner end of button 126 is counterbored to provideshoulder 128. Extending between shoulders and 128 respectively, iscompression spring 130 which acts to normally maintain driver 118positioned against the seat 112.

For aesthetic purposes after the tank is installed in the wall, operator13 at its head extremity can be provided with a cover plate 134 fordecorative purposes in association with wall 136 covering the tankinstallation. Plate 134 is maintained in mounted relation to the head102 by suitable screw means 138 and to the wall 136 by screw 140. Forcompliance with building codes in most communities an overflow pipe 150may be provided to extend through the top 64 into the upper portion ofthe tank and then vent laterally into the soil pipe 16 as shown, or downto the discharge pipe 56, not shown.

In the operation of the present device the tank is filled with waterthrough inlet supply line 14 and its connecting parts. The weight of thewater in the tank maintains ball 60 in closed position of the seat 40,as seen in FIG. 3, and the buoyancy of float 87 seals off the bore seat84 with its upper portion 90. Referring now to FIGS. 4 through 7,movement of the button 126 to the left compresses spring and results ina projection of point 122 into bore 48 adjacent the high side of theangularly disposed surface 44 adjacent bore 48. This distends orcompresses an edge of ball 60 and also moves the ball slightly towardthe low side of angularly disposed surface 44. allowing the seal to bebroken and water to pass through the discharge pipe 56 into the toiletbowl 10. When the seal is broken the ball rises as shown in FIG. 5 andwith the water flowing out through discharge 56 the float 87 drops fromits seated position shown in FIGS. 3 and 4. As the water is completelyevacuated, the float 87, with its concave bottom surface, seats the ball60 against the tapered surface of seat 40, as best seen in FIG. 6. Asthe water level rises, the weight of the solid end of the float 87maintains ball 60 against seat 40 until the volume of water in the tankis sufficient to maintain the ball in seated position. At this pointfloat 87 rises to its position of closing or sealing seat 86. It shouldbe noted that a tight seal does not have to be effected in any of theparts of the operator 18 since the passage of water past the free end ofthe operator acts like an aspirator and clears the operator of allpossible fluids therein. The entire operator 18 can be removed from thetank without turning off the water supply should point 122 or spring 130become worn.

A vent passage 150 provides communication between the upper end of thetank and the soil pipe or stack 16 to accommodate air passage to andfrom the tank as well as overflow if there should be a temporarymalfunction of the valves.

For clarity in illustration the water lines are not shown in FIG. 3since the relative position of the various components and the water aresubstantially identical to the view shown in FIG. 7. Further, it must bepointed out that the flow of water from inlet stub 72 through verticalmember 82 has been omitted from FIGS. 5 and 6 for clarity inillustration, it being understood of course that the water will commenceflowing to refill the tank simultaneously with the unseating of float 87from seat 86, with the large discharge bore 48 evacuating the tanksubstantially completely before refill is possible.

The angular disposition of upper surface 44 was selected to providemaximum contact between driver M3 and ball 60 as well as to create anunstatic surface for ball 60 to contact when establishing its seatedrelation with base 48. If the ball 60 contacts the right side of seat40, as seen in FIGS. 3 and 6, it will roll to the left to the bore 48.If it contacts the left side the water filling the tank will float it tothe right into seated position.

In the embodiment just disclosed the tank may be manufactured inmultiple sections from the reinforced plastic materials with theprojections 32 and 341 being extruded integral with the major wallportions of the tank and the top and bottom heat sealed or suitablyconnected thereto. In the event that code requirements are such thatthey demand a cast iron tank for this type of installation, then theinvention can be modified, as seen in FIG. 9, wherein similar parts bearsimilar numerals with the suffix a. The projections 32 and 34 replacedby longitudinally extending rod like members 160 which are suitablymounted in seat 40 and shut off mechanism 80 to vertically positionthese members within the tank as well as acting as the cage or retainingmeans for float 87 and ball 60.

A further embodiment of the invention can be seen in FIGS. 10 through 12wherein similar parts are designated by similar numerals with theaddition of the suffix b. The tank 12b is generally rectangular insection for accomodation between adjacent studs b within a wall section,as set forth hereinbefore. This embodiment is preferably made of plasticmaterials and includes, deside the sidewalls 28b and 30b a plurality oftransverse walls 180, 182 and 184 which extend substantially the entirelength of the tank and extend between the front and back walls. Thewalls 180 and 182 are apertured, as at 186 and 188 respectively toprovide a free communication between the various compartments on thetank, with the walls 180 and 182 being positioned laterally on oppositesides of the seats 86b and b to form the cage 36b for accomodation ofthe floating valve members b and 8712 respectively. The third transversewall 134 defines a second chamber, the upper end of which communicateswith the vent and overflow passage 150b. This is provided with a seat190 similar in configuration to the float 87b. The wall 184 withsidewall 30b forms a vent passageway 194 which communicates with anopening 196 at the lower extremity of the tank for purposes best setforth hereinafter. The

water level is omitted from FIG. with the floats centrally positionedfor clarity in illustration.

The operator 18b in this embodiment is provided with a plunger andbutton 1126b which is operable from the front side of the Wall and canutilize a spring return mechanism similar to the previous embodimentpositioned internally of the housing of the operator. Instead of thepoint contact with ball an being carried out by the driver M8 asprovided in the other embodiment, in this device there is provided aplate-like member 2M) pivoted adjacent its upper extremity bysuitablepin means 262. One or more rigid crescent shaped members 204 arepositioned on and extend laterally from plate-like member 2%). Plate 24Wis normally aligned in a plane perpendicular to the axis of and adaptedto be moved in an are by the linear actuation of plunger 126i; with thecrescent shape, sharply pointed members 204 being swung into contactwith and unseating the ball member 60b, the pivoted plate member 200substantially closing the bore 48b, as shown in phanton. Plate 291)prevents an initial rush of water through the bore dfib and therebyinsures that the hydrostatic head of water in the filled tank will notreseat the ball 60b when the members 2041 revert back to their initialposition. 7

Thus, when plate-like member 200 is in its open or normally verticalposition shown in FIG. 12 a free flow of water is possible with theextremities of sharply ended members 204 being positioned below the seatsurface 44b which permits the ball 60b to be seated in the same fashionas the other embodiment. When plunger 126b is actuated linearly andextended inwardly to rock plate-like member 200 about pivot means 202 toits closed or blocked position, shown in phantom, a small amount ofwater is initially allowed to enter the bore M1) and equalize thepressure on both sides of the unseated ball 60b thereby permitting ball60b to freely float upwardly. When operating pressure is relieved fromthe plunger I261; plate 200 returns to its normal position to permit thesubstantially complete discharge of the water from tank 12b through thebore 4%. The rush of water past plate 200 assisting in its return to thenormal position plus assisting the retrograde motion of plunger l26b toits initial positoin.

During the filling operation of this embodiment, after the seating ofball 6012, the water coming in through pipe 72b operating in the samemanner as previously described will raise the floats $712 and 1192 to apredetermined level whereby both the intake 72b as well as the vent andoverflow 1150b will be closed when the floats 87b and 1192 are seatedagainst seats 86b and 190 respectively.

The operator 18b in this embodiment which depends from and projectsbelow the tank bottom is provided with a downwardly extending forwardflange which is apertured to support the operator 18b between the wallof the discharge bore 4l8b and itself, for purposes set forthhereinbelow.

Associated with this embodiment is an anti-syphon device and themounting bracket 220. The device 220 is a generally box-shaped memberhaving downwardly extended end walls 222 suitably apertured as at 22d toaccept fasteners 226 for the mounting of the device relative to thestuds 20b. Device 220 has a base 22% preferably with a centralreinforcing flange 240, and front and back walls 232 and 234 are a pairof sloping surfaces 236 which extend downwardly from the side walls 222to a central bore 244) which extends through the 7 base 228. The centralbore 240 is larger than and adapted to freely accept a downwardlyextending projection from the tank 12 containing the bore 48b so thatthe bore 48b discharges directly through central bore 240 into thedischarge pipe 56b which is connected to the toilet 10b. In this fashionthere is an ambient condition in which the atmosphere is open to thedischarge pipe 56b during the egress of water from the tank. Without aclosed positive connection between the tank and the tube 56b, it isimpossible to have a syphoning effect. Extending upwardly from thesurfaces 236 are a series of notched curbed baffles 250 having loweropenings and upper notches to permit restricted egress of water past thebaffles to bore 240 and passage of air if the tank contacts the upperedge of the baffles. This prevents surges or the bankup of any fluids inthe event that there is an overflow through the opening 186 whichdischarges onto surface 236 in spaced relation from the central bore240. The tank 12b may be positioned directly atop the anti-Syphonmounting bracket 220 with suitable vertically disposed stop means, notshown, being provided for front and back stability of the tank relativeto the studs b.

In this embodiment the operator 18b is shown extending below the tank.It should be recognized, as was true in the previous embodiment that itis often desirable, should there be a malfunction in the spring orplunger means 126b that replacement be available with a minimum ofeffort. While this embodiment, in FIG. 12, shows the operator 18b withbore 48b and its attendant tubular portion as an integral part of thetank 12b, it should be recognized that this can be made a secon dary orremovable member which could be extracted through the wall and throughthe front wall 232 of the anti-Syphon means 220 by means of the slot 254or any other suitable arrangement.

The embodiments shown as tank 12 can be manufactured economically fromplastic materials such as glass filled polypropylene, polyethylene,poly-vinyl-chloride or any other material having the inherent structuralqualities necessary to overcome the bursting strength of the containedwater. The tank can be manufactured in many ways such as extruded withthe top and bottom walls carrying the various seats being suitably addedto the extruded walls; or the tank can be injection molded with eitherthe front or back wall added in a secondary operation; or the tank andits associated fittings could be therein formed from sheet stock and theparts suitably joined as by adhesives, heat sealing, or epoxy resins.The choice of materials and method of manufacture are limited only bythe designers experience.

An additional feature of this embodiment is the quickly installedsupport member 260 for the mounting of the toilet 10b. The supportmember 260 includes a pair of channeled members 262 having inwardlydirected flanges 264 extending longitudinally in predetermined spacedrelation. A plurality of apertures 266 are provided along one edge ofmembers 262 and spaced from the channel-shaped opening formed by theflanges 264, to accept suitable fasteners such as nails or screws tomount the channel members 262 to studs 20b. A pair of rigid, vertical,non-circular tubular members 270 are provided with transverse bores foraccomodating a plurality of tubular members 272. A plurality ofintermediate apertures 274 are provided in tubular members 270 spacedbetween the transverse tubular members 272 to accommodate a suitablefastenment to the toilet 10b. A soil pipe, not shown, can be acceptedwithin the other space between the members 272 and connected to a stack,not shown, as is normal practice.

Thus, the various embodiments of this invention disclose an economicalwater closet having its tank disposed between adjacent studs in an innerwall relationship and which with a few moving parts can provide acontact water supply for use in the discharge of solid waste materials.
